In order to achieve the above object, a method of a wireless guidance device and a facility of the present invention includes an induction electric signal and a danger prevention electric signal for instructing a visually impaired person from a sound wave signal generator. A radiated radio wave within a certain range is radiated into the air from an installed induction antenna such as buried underground in a road through a transmitter for a transmission line.

Then, a directional radio wave radiated in a certain range from an inductive antenna such as the underground buried on the road is received on the ground by an instructing reception signal through a walking cane carried by a visually handicapped person. By receiving it at a machine and letting the visually impaired sense it by hearing with an earphone or by tactile sensation due to vibration of a handshake, the visually impaired can smoothly guide the walk and provide a high degree of safety with wireless guidance. Equipment and facilities.

[Action]

According to the present invention, when a visually handicapped person walks, the visually impaired person's walking radio guiding device is used so that the visually handicapped person can independently act without any assistance such as assisting an accompanying person. Since it enables free walking with a high degree of safety, it provides a very favorable environment for visually impaired people to walk.

For visually impaired persons, the tiles etc. for visually impaired persons installed on the road surface are removed to prevent the danger due to the stumbling of the feet of ordinary persons and when a person with walking disabilities is traveling in a wheelchair. It is hoped that the obstacles will be resolved and that people with walking disabilities will be able to run smoothly in a wheelchair.
